Overview
Kage Avloppsren Verk is an advanced wastewater treatment plant in Västerbottens län, Sweden, serving approximately 5,821 people. It discharges treated water near the coast, with a designed capacity of 6,000 m³/day.
Kage Avloppsren Verk is a wastewater treatment facility located in Västerbottens län, Sweden, serving the local community of about 5,821 residents. The plant is situated near the coast in the municipality of Skellefteå, along the E4 highway. It operates as part of Sweden's municipal wastewater infrastructure, which is regulated under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the EU directive for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant has a designed capacity of 6,000 m³/day and currently discharges approximately 914 m³/day of treated effluent. The treated wastewater is discharged into a coastal environment, likely flowing into the Gulf of Bothnia via local watercourses. This area supports diverse aquatic life and is important for regional fisheries. The advanced treatment helps minimize nutrient loading, reducing the risk of eutrophication in the Baltic Sea, which is a sensitive marine ecosystem.
Environmental context
The plant discharges treated wastewater into the coastal waters of the Gulf of Bothnia, part of the Baltic Sea. This region is ecologically sensitive due to limited water exchange and high nutrient sensitivity, making advanced treatment crucial for preventing algal blooms and protecting marine biodiversity. The local watershed includes small rivers and streams that drain into the gulf, supporting fish populations and migratory bird habitats.
